APA is a complex system of citation. When compiling the reference
list, the strategy below might be useful:
1. Identify the type of source:
Is it a book? A journal article? A webpage?
2. Find a sample citation for this type of source
Check a textbook or the OWL APA Guide:
http://owl.english.purdue.edu/owl/resource/560/01/
3. “Mirror” the sample
4. Make sure that the entries are listed in alphabetical order and that
the subsequent lines are indented (Recall References: Basics)
Making the Reference List
In-text citations help readers locate the cited source in the
References section of the paper.
Whenever you use a source, provide in parenthesis:
• the author’s name and the date of publication
• for quotations and close paraphrases, provide the
author’s name, date of publication, and a page number
In-text Citation: Basics
When quoting:
•Introduce the quotation with a signal phrase
•Include the author’s name, year of publication, and page number
•Keep the citation brief—do not repeat the information
In-Text Citation:
Quotations
Provide the author’s last name and the year of
publication in parenthesis after a summary or a paraphrase.
In-Text Citation:
Summary or Paraphrase
Include the author’s name in the signal phrase, followed by
the year of publication in parenthesis.
In-Text Citation:
Summary or Paraphrase
When including the quotation in a summary/paraphrase, also
provide a page number in parenthesis after the quotation:
In-Text Citation:
Summary or Paraphrase
Introduce quotations with signal phrases, e.g.:
According to Xavier (2008), “….” (p. 3).
Xavier (2008) argued that “……” (p. 3).
Use such signal verbs such as:
acknowledged, contended, maintained,
responded, reported, argued, concluded, etc.
Use the past tense or the present perfect tense of verbs in signal phrases
when they discuss past events.
In-Text Citation:
Signal Words
When the parenthetical citation includes two or
more works, order them in the same way they appear in the reference
list—the author’s name, the year of publication—separated by a semicolon.
In-Text Citation:

When citing a work with two authors, use
In the signal phrase, use “and” in between the authors’
names
In parenthesis, use “&” between names
In-Text Citation:
Works with Two Authors
When citing a work with three to five authors, identify all authors in the
signal phrase or in parenthesis.
(Harklau, Siegal, & Losey, 1999)
In subsequent citations, only use the first author’s last name followed by
“et al.” in the signal phrase or in parentheses.
(Harklau et al., 1993)
In-Text Citation:
Works with 3-5 Authors
When citing a work with six and more authors, identify the first author’s
name followed by “et al.”

When citing a work of unknown author:
•use the source’s full title in the signal phrase

When citing an organization:
•mention the organization the first time you cite the source in the signal
phrase or the parenthetical citation.
•If the organization has a well-known abbreviation, include the
abbreviation in brackets the first time the source is cited and then use only
the abbreviation in later citations.
In-Text Citation:
Organization
When citing authors with the same last names, use first initials with
the last names.
(B. Kachru, 2005; Y. Kachru, 2008)
When citing two or more works by the same author and published
in the same year, use lower-case letters (a, b, c) after the year of
publication to order the references.

When citing interviews, letters, e-mails, etc., include the communicator’s
name, the fact that it was personal communication, and the date of the
communication.

author-date style. If electronic source lacks page numbers, locate and
